I just noticed this section on the forums, and thought I'd share some of my DIY's.
My greenwing's cage replacement (the light has been moved away since this pic)
The entire front of the base is a slide out drawer to hide food and toy's in rotation
I regularly change out the perches and rearrange them based on what he likes and actually uses. Here it is today
I've made a lot of toys, but never took any pics before they were torn up.
I'm going to start making and selling toys and perches that are reasonably priced to the bird community.
It'll keep me busy and help you guys from buying a stick for $30 just because its called a perch.
